Synopsis of adventive species of Coleoptera (Insecta) recorded from Canada. Part 4: Scarabaeoidea, Scirtoidea, Buprestoidea, Byrrhoidea, Elateroidea, Derodontoidea, Bostrichoidea and Cleroidea

Description:

A synopsis of adventive species of the Coleoptera superfamilies Scarabaeoidea, Scirtoidea, Buprestoidea, Byrrhoidea, Elateroidea, Derodontoidea, Bostrichoidea, and Cleroidea in Canada is presented. Of the 1611 species of those superfamilies recorded from Canada, 106 species in 74 genera and 18 families are reported as adventive, constituting 6.6% of the Canadian fauna of this group. Most adventive species belong to Scarabaeidae (25 spp.), Ptinidae (19 spp.), Dermestidae (15 spp.), Elateridae (10 spp.), Buprestidae (8 spp.), and Cleridae (6 spp.). Most species originate from the western palaearctic. Each species is reviewed and illustrated with color habitus photos. The Canadian distribution for each species is mapped and the general distribution in the USA is provided. General habitat information for each species is summarized and a taxonomic diagnosis is provided. One new species record is reported for Canada, the scarab, Nipposerica peregrina, and 27 new provincial and territorial records. Eucinetus terminalis LeConte is designated as a junior synonym of Eucinetus haemorrhoidalis (Germar), meaning that the latter species now has a holarctic distribution, and is removed from the list of adventive species in Canada.
